Job control on UNIX systems

-
I've been using control-z and fg to stop / resume programs from the UNIX terminal for as long as I've been using that environment. The problem is that I've only used those two commands so my usual workflow has always been "stack based". Meaning I have always used fg to resume the most recent program that I stopped.

Long story short, there is another command called jobs which enumerates all the programs which have been stopped. At this point you can use fg # to resume whichever job you want.

What a concept.

I found this web page had a nice description of all these commands:

In this case I had two squares with rounded corners, their sizes and the corner radius for both squares are configurable. Now I wanted a square tube to join these two pieces together. My hope was that I could get it close enough with some fancy parameters piped into the OpenSCAD linear_extrude function. It seemed possible since there are some pretty fancy parameters regarding rotations and twists. After checking out the documentation it didn't look like there was anything that would be close. For this project I found a module by Felipe C. da S. Sanches to create squares with rounded corners . I'm sure there are many like it, but this was the first one I found and it worked as advertised. So made a little module using this which wraps around a rectangle for ...

Taking Stuff Apart: Realistic Modulette-8

When I saw this fine piece of electronics at the landfill I knew it was special. Not only did it have a plethora of nice looking knobs and various shiny areas, but it also had a wooden enclosure. Although stamped steel cases are nice, its a little impersonal, not like this finely crafted device. I had already thrown it in the trunk before I even noticed - the thing was an 8-track player.

XCode4: UITabBarController with UINavigationController using Interface Builder

-
Image
If this helped you, please consider downloading my FREE  iPhone app " Hydrate Yourself "and leaving a review. There are a  whole   bunch  of  tutorials  to create a Navigation Controller inside a TabBarController with XCode3.  But there are a number of small changes in XCode4 which can trip up someone not familiar with them.  So this guide is essentially an updated version of those other guides, designed to create the same simple demo using the new tool. 1. Create a new Project We are going to start with a Tab Bar Application, so go ahead and create a new project as usual. I'm calling mine Navigation Tab Bar. 2. Select the Tab Bar Click MainWindow.xib and you should see the integrated Interface Builder. On the left is a section called Objects, select the Tab Bar Controller. 3. Add the Navigation Controller On the right side of your screen click the Utilities box. This is new in XCode4 and should look familiar if you've been...
